FREEHOLD TOWNSHIP – The condition of the fourth victim and sole survivor of a fatal multivehicle crash on Kozloski Road last week has improved to be “critical but stable,” authorities said.

The victim, a 25-year-old Freehold man, suffered massive head injuries and initially was in “extremely critical condition,” according to First Assistant Prosecutor Marc LeMieux. Authorities are withholding the man’s identity.

The Monmouth County Prosecutor’s Office used the media to find witnesses to help with the investigation.

“The media push did assist in providing three witnesses to the crash,” LeMieux said.

The crash involved three vehicles, a Honda Pilot, Volkswagen Jetta and Toyota Camry and it happened on a sunny afternoon on Aug. 19. Two people were in the Jetta and one person each was in the Pilot and Camry.

Investigators continue to piece together why the southbound Jetta went into the oncoming lane, he said.

“Why that happened is still under investigation,” LeMieux said.

Pronounced dead at the crash scene were Noelle DeLuccio, 20, of Howell and Nicholas Dever, 19, of Freehold in the Jetta, driven by Dever. The Jetta collided with a 2006 Honda Pilot driven by Thomas J. Koller, 50, of Freehold Township, also pronounced dead at the scene.

DeLuccio and Dever were the parents of a daughter, Mikayla, who was the first born baby in Monmouth County in 2013. Koller left behind a wife of 20 years and two daughters, according to his obituary.

The fourth victim was alone in the Camry when the Honda went airborne and landed on the Camry’s roof, causing a severe head injury to the driver, authorities said. After he was extricated, the man was flown by helicopter to Jersey Shore University Medical Center in Neptune.
